TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 307,943, dated November 11, 1884-.

Application filed August 29, 1884. (No model.)

T0 and whom it may concern.-

Be it known that I, ADAM HOFMANN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Road-Carts, of which the following is a specification.

My invention relates to that class of roadcarts in which the body is mounted on two wheels, and the shafts are fulcrumed to the forward end of the body and extend backward from said fulcrum.

The object of my improvement is to connect the rear ends of the shafts to the body in an improved manner, whereby a rocking motion of the body is prevented, and the fulcrums of the shafts are relieved from a lateral bending strain in turning the vehicle.

The accompanying drawings illustrate my invention.

Figure l is a side elevation having a portion of the side broken away. Fig. 2 is a plan having the seat removed. Fig. 8 is a detached perspective view of one of the shaft-irons.

A represents the body of the vehicle. b I) are the shafts. To the under side of the rear ends of each shaft is rigidly attached,by means ofbolts or clips, a shaft-iron, c. In the forward end of said iron is formed an eye, (Z. Said eye is screw-threaded, and is adapted to receive a screw-threaded stud, e, which is secured to the forward part of the body-sill f,

' thus forming a fulcrum on which the shaft may oscillate vertically with the motions of the horse. The rear ends of the shaft-irons are turned inward and upward, so as to pass above the upper side of the sill f, and are then turned inward through slots 9 in opposite sides of the body, thus forming arms h h, their inner ends being cylindrical and engaging eyes i, turned on the free ends of fiat springs j j,

which are held thereon by nut-s screwed on the inner ends of said arms. The springs j extend backward, and are secured at their back ends to the top side of the sills f. To prevent rattling rubber sleeves 7c are placed over each of the arms h, and to prevent the wearing of the slots in the body slotted plates Zare secured to the body. The body is mounted on springs secured to a single axle in the usual well-known manner. If desired, eyes (Z may be formed separately from the shaft-irons without departing from the spirit of my invention.

By the above-described construction, the shafts being fulcrumed to the outside of the body, and the springs j secured to the inside, the ends of the shafts are free to oscillate vertically, and are each supported at their rear ends against lateral strain in turning by the springs j engaging the inside of the body, and the tendency to bend the studs e is avoided.

I claim as my invention 1. The combination, with a twowheeled vehicle having shafts'fulcrumed at or near the forward end and on the outside of the body thereof, and extending backward fromthe fulcrum, of inwardly-turned arms rigidly secured to said shafts and passing inward through slots in the body, and springs secured to inside of said body, and having their free ends connected with said arms, substantially as and for the purpose specified.

2. The combination, with a two-wheeled vehicle having shafts i'ulcrumed at or near the forward end and 011 the outside of the body thereot,and extending backward from the ful crum, of a pair of shaft-irons adapted to be secured to saidshafts, and each having an eye, (I, and an inwardly-projecting arm, h, and a pair of springs, j j, secured to the inside of said body and adapted to engage said arms h, all substantially as specified.

ADAM HOFMANN.
